Between midnight July 4 and 8 a.m. July 5, Des Moines police received 1,199 calls; nearly half were related to fireworks. In 2017, Des Moines police received 270 fireworks-related calls when they were still legal to set off within city limits.

Fireworks calls are a drain on police department resources, forcing officers to go and investigate the calls, Parizek said.

"Fortunately, we didn't have any major crime issues or else that would have been a mess," Parizek said. "You see the burden on the system."

Enforcing fireworks violations can also be a challenge. Police don't actually see someone lighting off a firework and most of the calls they receive are noise complaints, said West Des Moines Police Lt. Anthony Giampolo.

Residents who do see their neighbors lighting off fireworks are also hesitant to testify in court.

In February 2017, the Des Moines Register published an Iowa Poll showing 65 percent of Iowans supported legalizing fireworks as a bill regulating their use and sale was working its way through the state legislature.

But a few months later, after fireworks had been legalized, support for them dropped. After July 4, just 45 percent of Iowans supported legal fireworks in the state. An Iowa Poll published this February, however, found that only 39 percent of Iowans wanted to repeal the law and that 53 percent would oppose a repeal.
